IVAN KING, OF LOS ANGELES, CALIFORNIA.

REEL-OVEN.

Application filed April 22, 1918.

To all to from it may concern:

Be it known that I, IVAN KING, a citlzen of the United States, residingat Los Angeles, in the county of Los Angeles and btate of California,have invented a new and useful Reel-Oven, of which the following. 1s aspecification.

My invention relates to bakers ovens, be ing more particularly the typeof oven commonly termed a reel oven whlch is used for the purpose ofbaking cookies, crackers, cakes, bread and similar articles. Ovens ofthis type are generally constructed with the door of the oven arrangedin the wall of the oven adjacent to the nearest point of the reel to thewall, which places the door approx1 inately half way between the top andthe bottom of the reel. I11 opening the door of an oven so constructedit will be readily understood that the heat of the oven, particularlythe heat in the lower half of the oven, will very quickly pass out ofthe door thereby lowering the temperature of the oven to a great extent.i

The principal object of my invent on is to produce an oven of the classdescribed, of simple form and constructlon, 1n which the door of theoven is placed at or below the lowest portion of the reel and in linewlth or below the floor of the oven.

Other objects and advantages will appear hereinafter from the followingdescription.

Referring to the drawings, which are for illustrative purposes only,

Figure 1 is a vertical sectional view of an oven embodying a form of myinvention.

Fig. 2 is a front elevation of the oven shown in Fig. 1 on reducedscale, a portion of the face of the oven being broken away to show theinterior thereof.

Fig. 3 is a diagrammatic view of an oven embodying another form of myinvention.

11 designates an oven, 12 the front wall, 13 the rear wall and 14 acurved top wall. 15 designates the floor of the oven having a series ofopenings 16 formed therein cominunicating with the fire box 17 formedunder the floor of the oven. 18 designates the doorof the fire boxthrough which ex tends an oil burner 19, and 20 designates a flueconnecting with the stack 21.

Extending through the oven and supported in suitable bearings 22 in thesi e walls of the oven is a shaft 23 upon which Specification of LettersPatent.

is secured two large sprocket wheels 24 forming the reel. These sprocketwheels 24 support an endless carrier which consists of sprocket chains25, between which chains are plvotally supported a series of trays 27which extend across from one chain to the chain 25 on the oppositesprocket wheel.

A loop 30 is formed in each chain 25 by extending the chain forwardly asshown in Fig. 1 over a smaller sprocket wheel 31, an idler 32 beingprovided for guiding the return or upper portion of the loop to thesprocket wheel 24. The front wall 12 of the oven is extended forward asindicated at 34 and is provided with a door 35 throu h which access ishad to the interior of t1e oven. 36 designates a lass plate or windowthrough which the interior of the leak ing chamber of the oven may beinspected.

4O designates a gear wheel secured to the shaft '23 on the outside ofthe oven which is driven by a spur gear 41 from a motor 42 therebydriving the chains and carrying the trays therewith through the oven.

The oven is operated by setting the motor in operation which drives theshaft 23 through the connections heretofore described thereby drivingthe sprocket wheels 24 and chains thereon which carry the trays throughthe path of the sprocket chains in the direction of the arrow shown inFig. 1. As the trays'on the lower run of the loop 30 approach the door35 suitable pans carrying the material to be baked are placed upon thesame as they pass the door opening, and when so placed travel upwardlyto the highest part of the oven and then continue to the lowest part ofthe sprocket wheel where they enter the loop and are brought forward tothe door.

In the form shown in Fig. 3 the loop indicated at extends downwardlyfrom the sprocket wheels instead of forwardly, it being understood thata loop is formed in the carrier, that is, the sprocket chains, either ator below the main floor of the oven so that the heat is not lost fromthe oven by reason of opening the door during the operation.

The oven chamber is formed with an extension in the forward part of thesame and the door is in the front of such extension. The loop in thechains extends into such extension away from the body of the ovenchamber and toward the door. With this construction the door does notexpose the oven chamber proper nor directly disturb the heat therein.

What I claim is 1. An oven comprising an oven chamber, a door for theoven chamber, a rotatable reel in the chamber, an endless carriersupported on the reel, trays mounted on the carrier, and a loop formedinthe carrier extending away from the reel toward the door, the

lower run of said loop extending tangentially forward from the lowestpart of the reel.

2. An oven comprising an oven chamber an extension in the forward partof said chamber, a rotatable reel in the chamber, an endless carriersupported on the reel, trays mounted on the carrier, a loop formed inthe carrier extending away from the reel into said extension, and a doorin said extension through which the trays on the loop are accessible.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 13th day oi April, 1918.

IVAN KING.
